Embodiment Construction

[0027] A kind of PVC imitation marble plate manufacture method, comprises the following steps:

[0028] 1. Crushing the recycled materials of PVC products or templates to obtain the main PVC material after crushing;

[0029] 2. Add heavy calcium, light calcium, stabilizer, ACR modification, CPE toughening agent, titanium dioxide, stearic acid 1801, and paraffin to the PVC main material in sequence, and mix and stir to obtain a mixture;

[0030] 3. After the mixture is placed in a twin-screw extruder for extrusion production, a PVC imitation marble slab of a certain specification is obtained through an extrusion die;

[0031] 4. Cooling the obtained PVC imitation marble slab to obtain the formed PVC imitation marble slab.

[0032] Wherein, the crushing of recycled materials of PVC products or templates includes:

[0033] Crushing the recycled material of the PVC product or formwork to obtain the first pulverized PVC main material;

[0034] After the first pulverized PVC main...

Abstract

The invention relates to the technical field of stone plastic and particularly discloses a manufacturing method of a PVC marble-imitated plate. The method includes following steps of: smashing reclaimed materials of PVC products or templates to obtain a smashed PVC main material; adding ground calcium carbonate, precipitated calcium carbonate, a stabilizing agent, an ACR modifier, a CPE flexibilizer, titanium dioxide, stearic acid 1801 and paraffin into the PVC main material, mixing and stirring to obtain a mixture; adding the mixture into a twin-screw extruder, and extruding to obtain a PVC marble-imitated plate with a certain specification through an extrusion die head; cooling the PVC marble-imitated plate to obtain the formed PVC marble-imitated plate. The method is advantageous in that problems namely color fading and deformation, and the like, of stone plastic materials in traditional techniques are overcome; and the PVC marble-imitated plate has advantages of light weight, wear resistance, flame retardance, skid resistance, moisture resistance, and the like.

Description

technical field [0001] The invention relates to the technical field of stone plastics, in particular to a method for manufacturing a PVC imitation marble plate. Background technique [0002] As we all know, PVC sheets are divided into coils and sheets, and imitation marble sheets specifically refer to sheets. From the structure, it is mainly divided into homogeneous solid sheet, multi-layer composite sheet, semi-homogeneous transparent sheet; from the shape, it is divided into square material and strip material. [0003] Since the stone-plastic composite material conforms to China's industrial policy of "constructing a resource-saving and environment-friendly society" and "sustainable development", it has developed rapidly as soon as it appeared. Especially in today's increasingly serious problem of greenhouse gas emissions, the implementation of "low-carbon economy" has further reflected the value of stone-plastic composite materials. China's natural stone resources are d...
